Answer:A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms. That being said, certain land organisms are useful in young rocks and specific regions.
Explanation:
Use Sammi's model as an example to explain why cells are the building blocks for human bodies.
Answer:
Sammi's model uses common materials to represent the different parts of the circulatory system. These different parts represent the heart, blood vessels, capillaries, and digestive tract. The model shows that blood is pumped by the heart through the blood vessels, then through the capillaries located in the digestive tract, and back into the blood vessels. Sammi's model also shows that clear water becomes green after traveling through the cardboard tube, which represents the digestive tract and capillaries. This is because the particles lined in the cardboard tube are absorbed into the water. This is much like the circulatory system because blood travels through the capillaries and absorbs the nutrients stored in the villi, which are represented by the corrugated inside of the cardboard tube, that absorb nutrients from the digestive tract. The blood then travels back into the blood vessels to deliver this nutrients throughout the rest of the body, which is vital for the function of all organs in the body.
This model supports that cells are the building blocks for human bodies because it shows how each part of the digestive and circulatory systems work to move cells around in the body in order to provide nutrients and required substances to keep the body functioning properly. If the digestive and circulatory systems were not functioning, the body could not function either because the nutrients and cells that are transported by these systems are required for life of the human body.
Explanation:
This is my own personal answer, so if there are any mistakes please feel free to correct me. You may want to paraphrase or change parts of this answer. I hope this helps! Have a wonderful day! :)
Cells are the building blocks for human bodies because cells have different parts and each performs specific functions.
A cell refers to the smallest, basic unit of life. The model uses common materials to represent the different parts of the circulatory system.
From the model, it can be seen that some of the parts that are represented include the heart, blood vessels, capillaries, and digestive tract. This illustrates that for blood to be pumped into the body, different organs have specific roles to play just like the cells have different functions to play in the human body.

Explanation:
Chromosomal rearrangements are considered large-scale mutations. Point mutations are considered small-scale mutations, and are of two general types. The first is a single nucleotide-pair substitution. What occurs here
Answer:
Please find the explanation of what single nucleotide-pair substitution is below
Explanation:
Point mutation is considered a small scale mutation as stated in this question because it involves only ONE nucleotide in a sequence i.e. only one nucleotide base is changed or altered in the sequence.
Single nucleotide-pair substitution is a type of point mutation in which one (single) nucleotide base is replaced by another nucleotide base. For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG
Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.

In a warehouse, the workers sometimes slide boxes along the floor to move them. Two boxes were sliding toward each other and crashed. The crash caused both boxes to change speed. Based on the information in the diagram, which statement is correct? In your answer, explain what the forces were like and why the boxes changed speed.
Answer:
A: Box 1 has more mass than box 2
Explanation:
The liner momentum of the boxes before and after the crash. Since the larger box has more mass then it's velocity will create a larger impact upon the smaller box because it is heavier it's speed would increase before impact and since the othe box was smaller it's speed would be slower..

What is the correct sequence of events for the cell cycle ?
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Explanation:
The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S) (mitosis, or M, stage).
What is the cell cycle?Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2.
A cell's growth and division are accompanied by a sequence of processes known as a cell cycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Therefore, in eukaryotes, the cell cycle consists of four different phases: G1, S, G2, and M divide the cell.

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
Enzymes do not affect the energy of a reaction.
Enzymes slow down reactions so products can form.
Enzymes can be reused because they do not permanently bond with substrate.
Enzymes can only bind to other enzymes so the same product is formed each time.
Answer:
Enzymes can be reused because they do not permanently bond with substrates.
Explanation:
Enzymes can be reused because they do not permanently bond with substrates is the factor makes enzymes well-suited to the role of catalyst in a biochemical reaction.
what are the property of enzyme ?Enzyme are the Proteins serve as biological catalysts by increasing the rate of chemical reactions.
The enzymes act upon the substrates which form new molecules known as products, they are substrate specific.
enzyme Specificity indicate the linkage type the enzyme acts on. Completely specific enzymes would act only on a particular chemical structure, rather than several kinds of similar molecules.
When molecules undergo a chemical reaction, the atomic bonds in the reactants are broken and form new bonds which further form a new product is called the Chemical Reaction.
They act as a biological catalyst and can speed up a reaction affected by pressure, pH and temperature. Reactions are reversible.

Grapes harvested and crushed into juice will often produce a fermented beverage containing alcohol. Grains (such as wheat, barley, rye, or corn) will also produce an alcoholic beverage if they are soaked and allowed to ferment. Which of the following organisms, naturally present in the environment, is the likely cause of the fermentation?
a. angiosperms
b. yeasts
c. basidiomycetes
d. ciliates
Answer:
b. yeasts
Explanation:
According to this question, certain crops and grains that contains sugar such as grapes, wheat, barley, rye etc. produce an alcoholic beverage via fermentation. This fermentation process is naturally carried out by YEAST cells.
Yeasts are fungi capable of undergoing both aerobic and anaerobic cellular respiration (fermentation) depending on the availability of oxygen. Fermentation carried out by yeasts breaks down sugar in substances to alcohol (ethanol). In other words, the sugar contents of those crops is being broken down into alcohol by fermentation process carried out by YEASTS.
